本书专门讲述了GDI+编程中与开发自定义控件相关的功能，重点放在Windows Forms自定义控件的创建上，同时也讨论了ASP.NET服务器控件的创建问题。全书共分为4个部分：第1部分是对GDI+的用途和结构的概述，第2部分结合代码实例讲述了GDI+编程的具体细节，如绘图表面、坐标系、钢笔和笔刷、文本和字体、图像和图像操作、路径和区域、变换的处理和打印等。其中涉及了GDI+在自定义控件中的应用最相关的所有的类、方法、属性和事件。第3部分集中讲解了自定义控件的设计和开发，包括自定义控件的定义、特征，控件与VS.NET的集成，在控件中如何实现滚动等。第4部分讲述了GDI+功能在Web应用程序中的使用。如在Internet上提供了GDI+图像、创建ASP.NET服务器控件使用GDI+创建Web服务等知识。-Book devoted to the GDI+ programming and development of custom controls-related functions, focusing on Windows Forms custom control creation, and also discussed the creation of ASP.NET server control problems. The book is divided into four parts: Part 1 GDI+ is an overview of the purpose and structure, Part 2 with code examples about the details of GDI+ programming, such as the drawing surface, coordinate system, pen and brush, text and fonts , images, and image manipulation, paths and regions, transformation processing and printing. Which involves the GDI+ application in a custom control all the most relevant classes, methods, properties and events. Part 3 concentrates on the design and development of custom controls, including the definition of custom controls, features, controls and VS.NET integration, how to scroll in the control and so on. Part 4 describes the GDI+ functionality in Web applications to use. Available on the Internet, such as GDI+ images to create ASP.NET server con
